Summary

visual and acoustic survey of the Eastern Caribbean Islands from St. Kitts to Trinidad, and from Venezuela to

Guadeloupe, was conducted from

February to

April 2000 for humpback whales on the 224 foot

NOAA

research

vessel Gordon Gunter. The survey involved scientists from several Southeastern Caribbean nations and the United

States, and was sponsored

IOCARIBE- This report presents the preliminary fmdings of this survey. Three or

four observers using

150

mm objective binoculars and handheld binoculars maintained a visual watch. The acoustic

survey was conducted using directional (DIFAR) sonobuoys. Acoustic and visual whale detections of humpback

whales were compared.

DI'MODUCTION

The

NOAA

Ship

Gordon Gzwter

departed Pascagoula, Mississippi on

February 2000 to

conduct a survey of humpback whales

(Megaptera novaeangliae)

and other cetaceans in coastal,

shelf and deep waters of the Southeastern Caribbean Islands, the "Windwards" (Fig.

1).

This

survey was sponsored

the National Marine Fisheries Service's

(NMF S)

Southeast Fisheries

Science Center (SEFSC),

and the International Oceanographic Commission's IOCARfBE

organization, a multinational organization for the coordination of marine research in the wider

Caribbean. The scientific staff included researchers from a number of Southeastern Caribbean

nations and the United States. The purpose of this survey was to visit areas where humpback

whales were previously hunted to depletion

commercial whalers, and to determine whether

the whales have recovered and re-occupied these areas. Previous research indicates that

humpback whales migrate from summer feeding grounds in the North Atlantic to winter mating

and calving areas in the northern West Indies and south to the northern coast of South America.

Whales from the eastern United States, eastern Canada, Greenland, Iceland, and Norway all mix

spatially and breed in the West Indies, but their status in the Southeastern Caribbean has not

been assessed. Humpback whales will be the subject of a Comprehensive Assessment

the

International Whaling Commission in June 200

and scientific information on the status of

humpback whales in the Southeastern Caribbean is relevant to that assessment, and is relevant to

U.S.

management requirements for endangered whales under the Marine Mammal Protection

Act and the Endangered Species Act. In addition to humpback whales, opportunistic

observations and biopsy samples were collected from other cetacean species that were

encountered in the Southeastern Caribbean-

OlUECTIVES

Assess current distribution and relative densities of humpback whales in historically

important habitats.

2- Photograph and biopsy sample humpback whales for individual identification, as well

as toxicological and stable isotope analyses, to determine-the relationship of these whales

with

the greater North Atlantic population.

Opportunistically obtain biopsy samples of other cetacean species, including Bryde's

whales, sperm whales and other odontocetes.

4. Opportunistically collect data on the distribution and relative densities of seabirds and

other marine life.

Collect associated environmental data at survey locations.

COUNTRY

CLEARANCES

Clearance to conduct this survey in the waters of the nations of the Southeastern Caribbean was

requested in August

1999,

six months prior to the beginning of the survey in February 2000

(Table

1).

Clearance for this multinational survey was received from the Dominican Republic,

St. Kitts and Nevis, Antigua Barbuda, Guadeloupe-Marie Galante, Martinique, St. Lucia, St.

Vincent and the Grenadines, Barbados, Grenada. Trinidad-Tobago, and Venezuela. Clearance

was not received from Dominica, Antigua, Barbuda and St. Vincent and Grenadines. When the

survey arrived at the waters of those countries that had not provided clearance, all scientific

operations were suspended and the vessel proceeded

right of innocent passage through that

nation's waters. Scientific operations resumed once the vessel had entered the waters of a nation

that had provided clearance for the survey.

METHODS

Data on the presence and distribution of cetaceans were collected using visual observers

in conjunction with passive acoustic monitoring, Humpback whales were considered the primary

species and were located visually and acoustically. Photographs and biopsy samples were

obtained for individual identification.

All

other cetacean species opportunistically encountered

were recorded, and when possible, photographs and biopsy samples were obtained.

Visual Survey

Visual survey operations for cetaceans were conducted using two teams of three

observers during daylight hours, weather permitting (i.e., no rain, Beaufort sea state

<7,

winds

approximately 22 kts.). Each team consisted of marine manimal observers experienced in

shipboard cetacean observation and identification techniques. Two observers searched for

cetaceans using 25X "bigeye" binoculars mounted on the ship's flying bridge. The third observer

recorded data and maintained a search of the area near the ship using unaided eye or

hand-

held binoculars. Data were recorded on a laptop computer using a data acquisition and logging

software program that interfaced with the ship's a global positioning system

(GPS).

Environmental data recorded included sea state, surface temperature, water depth, weather,

visibility, wind direction and speed, and sun glare in the observer's field of view. Cetacean

sighting data included species, group-size, presence of calves, bearing from the bow, linear

distance from the ship when detected, and behavioral observations.

In accordance with Research Permit No.

779-IJ39

issued to the

SEFSC by

the National

Marine Fisheries Service Office of Protected Resources, data on behavioral responses of

cetaceans to the survey vessel were recorded.

complete record of this information may be

obtained from the SEFSC's Pascagoula Laboratory.

Acoustic

The acoustic survey was conducted using DIFAR directional sonobuoys. These

sonobuoys contain a compass in the sensor head and transmits continuous signals containing

directional information on sound sources back to the ship. The buoy transmits these sigrtals on a

VHF radio carrier in an analog multiplexed format which is de-multiplexed to extract the

direction information in degrees magnatic: from the sonobuoy to the sound source. The magnetic

accuracy to a sound source using these buoys has a standard deviation of two degrees. Calling

whales were detected on two or more buoys separated

several kilometers baseline distance,

and the magnetic bearings to the source of the calls from the buoys determined. When two or

more bearings crossed with a sufficient baseline separation it was possible to precisely locate the

position of a calling whale. The ship was then directed to the location of the calling whale and

attempts were made to locate the whale visually.

Technical Memorandum describing

the details of the passive acoustics activities and methods utilized during this survey may

obtained from the Protected Species Branch,

SEFSC,

Miami Laboratory.

Cetacean Biopsy Samplin

Biopsy samples of skin and blubber were collected from humpback whales and other

cetacean species encountered during the survey. Samples of skin and blubber approximately

0.75

cm were collected

by SEFSC

staff authorized as collection agents under

CITES

permit No.

99USO 1

5415/9 and Endangered Species Act

(ESA)

and Marine Mammal Protection

Act

(MMPA)

permit No. PRT 10233 issued to the United States National Museum of Natural

History. Samples were collected for genetic analyses to determine the relationship of humpback

whales in the southeastern Caribbean to the greater North Atlantic population, toxicological and

stable isotope analyses. Samples were collected using either a modified crossbow or a modified

.22 caliber dart rifle. Both of these sampling devices were fitted with specially designed darts

tipped with biopsy sampling heads that extract a small plug of tissue from the animals. Biopsy

sampling was conducted from the bow of the

Gordon Gunter

as well as from rigid-bottom

inflatable boats that were launched ftom the

Gordon Gunter. 6ata on each biopsy sampling

attempt were recorded in a log book, and included the date, time, platform, sampler and recorder

names, field number, sampling device, species sampled, location

(GPS),

number

attempts

(successful and misses), body location struck and sampled, and behavioral reaction of the

subject animal.

complete log of biopsy sampling operations and activities may be obtained

from the

SEFSC

Pascagoula Laboratory.

PhotoQxWhLc Identification

Vanations; of dorsal humps and pigmentation patterns on the underside of the tail flukes

of humpback whales can be used to identify individual animals. Photographs were taken on

black and white

ASA

400 film with

mm cameras equipped with

200-300

mm telephoto

lenses. Attempts were made to photograph all whales and especially those from which biopsy

samples were obtained Other species of cetaceans were opportunistically photographed for

species identification.

Environmental Data

Water temperature data were collected using a

SBE9/11

Continuous Time Depth

(CTD)

recorder at the request of the acoustic team leader to provide a temperature-depth profile to

model the transmission of sound at depth. Additional environmental information from

shipboard sensors was recorded

the shipboard Scientific Computer System

(SCS).

The

SCS

continuously displayed and recorded the ship's position, heading and speed, wind speed and

direction, barometric pressure, sea surface and air temperature, and water depth.

RESULTS

Cetacean Visual Surv

During the

3 7

days at sea, a total of 45 84 Ian were surveyed on effort during daylight

hours (Table 2, Fig.

1)-

Daily effort ranged up to 14.6 hours/day and 242 km/day and averaged

7.5

hours/day and 124 km/day.

total of

196

cetacean groups were sighted (Leg

1, 68

groups

Leg 2,

128

groups) (Tables

4 and

Fig- 2-

10).

At least

cetaccan species were observed-

The highest number of cetacean groups sighted on one day was 20 on March

26,

2000 during the

transect south

Puerto Rico (Table

3).

The most commonly sighted species were humpback

whales (n

= 3'

:)),

bottlenose dolphins

(Tursiops truncatusXn

19),

and sperm whales

(Physeter

macrocephalus) (n

= 16)

(Table

3).

the

sightings of humpback whales,

were of single whales, 2 sightings of three

whales, and

sightings of 2 whales (including two cow-calf pairs). Humpback whale mean

group size was 1.4 (Table 4). Humpback whales were seen in both shallow and deep water.

Water depths at sighting locations ranged from

5029

m with a mean depth of

586

m (Table

4). The largest groups of other cetaceans observed included a group of

175

pantropical spotted

dolphins (Stenella attenuata)

and a group of

175

spinner dolphins

(Stenella longirostris).

Spinner dolphins had the largest mean group size with

105

animals per group.

While humpback whale song was heard throughout the entire survey area (see Acoustic

Survey below), except for three sightings north of Puerto Rico, visual sightings of humpback

whales were made only in the areas from Guadeloupe south to Trimdad-Tobago and Venezuela

(Fig.

3).

The few visual sightings of humpback whales compared to the number acoustic

detections of singing whales is attributed to the generally high Beaufort Sea State

(5+

average) and the relatively brief periods that humpback whales spent at the surface. Eighteen

humpback sightings occurred in waters east of Trinidad and Tobago (including one cow-calf

pair),

in Guadeloupe and Marie Galante waters, and 2 sightings each off Barbados and

Martinique, one sighting off Venezuela, and the remaining sighting of a cow-calf pair off

southern end of Grenada (Fig.

3)^

Sightings of three species of odontocete cetaceans off Trinidad-Tobago and Venezuela

were of particular note. Observers agreed that these animals appeared to be smaller than the

same species found in the Gulf of Mexico. This size difference was first noted when a group of

what appeared to be Atlantic spotted dolphins or bottlenose dolphin came to ride the bow of the

Gordon Gunter.

These animals were all approximately the same size and at first appeared to be

juvenile bottlenose dolphins. However upon closer examination it was noted that some animals

in the group were spotted like Atlantic spotted dolphins. This size variation was also noted in a

group of rough-toothed dolphins

(Steno bredanensis)

encountered off the east coast of Trinidad,

and a group of spinner dolphins north of the Venezuelan and Trinidad border.

Associations between cetacean species were noted on five occasions. On two occasions

rough-tooth dolphins were associated with humpback whales. In both cases the rough-tooth

dolphins were observed from the small inflatable boats while approaching a humpback whale

during attempts to obtain biopsy samples. In both instances the rough-toothed dolphins

attempted to ride the small boat's bow wake. Pilot whales were sighted in association with

Fraser's dolphins

(Lagenodelphis hosei)

and Atlantic spotted dolphins were associated with the

smaller boftlenose/Atlantic spotted dolphins noted in the previous paragraph.

Acoustic

small number of sonobuoys were deployed while tratisiting through the Gulf of

Mexico and along the southern sides of Silver and Navidad Banks north of the Dominican

Republic to test and calibrate the passive acoustic recording and tracking systems. Passive

survey effort began when the vessel reached the waters of St. Kitts and Nevis.

total of

176

sonobuoys were deployed throughout the study area.

total of

sonobuoys were deployed

during Leg

(Fig.

11).

Survey effort for Leg 2 began in Venezuelan waters and a total of

sonobuoys were deployed. These included

sonobuoys depl4ed near and to the north of

Puerto Rico and the northern coast of the Dominican Republic to obtain recordings of humpback

song for comparison with song recorded in more southerly areas (Fig. 12).

Humpback whale song was detected throughout virtually the entire area surveyed in the

Southeastern Caribbean.

number of islands were not surveyed acoustically either due to time

constraints or lack of clearance to conduct surveys those waters. The number of acoustic

detections derived from the sonobuoy tapes was used to estimate the number of singing

humpback whales along that portion of the survey track line. The estimated number of singing

whales in each area.surveyed is shown in Table

6. A

total of

singing whales were detected

during "on effort" surveys during Leg

and 44 during Leg 2 of the survey. This is compared to

and

humpback whales sighted during the same "on efforf

survey in Legs

and 2,

respectively. The greater number of acoustic detections relative to visual sightings demonstrates

the advantage of passive acoustic over visual methods for surveys in these areas and during

environmental conditions that severely limit the effectiveness of visual methods. Future analyses

of these data will form the basis of an estimation of the relative density of humpback whales in

the Southeastern Caribbean.

Cetacean Biol)s

Nineteen biopsy samples were obtained during the cruise (Leg

= 3;

Leg 2, n

= 16)

(Table

7).

Humpback whale biopsies were considered the primary objective, and three skin and

blubber samples were collected (Fig-

In addition, six other species were sampled including

Atlantic spotted dolphin (n

= 1),

Common dolphin (n

8),

Bryde's whale (n

= 1),

bottlenose

dolphins (n

4), and pantropical. spotted dolphins (n 2) (Figs.

133

andl4). Humpback whale

biopsy samples were sent to Dr. Per

Palsboll at the University of Wales Bangor, United

Kingdom for analysis, archiving, and comparison with the North Atlantic humpback whale

population genetic database.

All

other biopsy samples were sent to Dr. Patty Rosel at the

NOAA,

National Ocean Service

(NOS)

Laboratory in Charleston, South Carolina for analysis

and archiving.

Environmental data

Profiles from the

SBE 9/11
